Falling blocks,
clear the rows.

Falling Blocks is a block-stacking puzzle game in the classic tetromino tradition. Pieces of four squares fall from the top of the board, and your job is to rotate and slide them into rows. Completing a full row clears it and scores points.

Left and right arrows move the falling piece. Down softly drops it for extra score. Space hard-drops it instantly. Up or X rotates clockwise, Z rotates counter-clockwise, and C holds the current piece for later. Press P or Escape to pause.

Pressing C stores the current piece in the hold slot and swaps in whatever was already there. You can only hold once per piece — after you place a piece, hold becomes available again. Use it to save an I-piece for a four-line clear.

A single line scores 100 × your level, a double scores 300 × level, a triple 500 × level, and a four-line clear (the maximum) scores 800 × level. Soft drops add 1 point per cell and hard drops add 2 points per cell, so aggressive play also pays.

You level up every ten lines cleared. Each new level increases gravity, so pieces fall faster and you have less time to react. Higher levels also multiply your score, so faster play is more rewarding.

The ghost piece is the faint outline showing exactly where the current piece will land if you hard-drop. It removes guesswork and lets you focus on placement decisions instead of timing.

Keep your stack as flat as possible and reserve one column on the side for I-pieces — that lets you stack three rows and clear all four at once for the biggest score. Use the next-piece preview and the hold slot to plan two or three pieces ahead.

Yes. The on-screen controls support swipe gestures for movement, tap to rotate, and a dedicated hold button. The board scales for vertical phone screens.
